Benefits of technology

[0006] In view of the above-identified circumstances, it is therefore the object of the present invention to provide an observation apparatus having a temperature regulation mechanism that can accurately retain the heat and regulate the temperature of the object of observation.

Problems solved by technology

Publication No. 3-25598 are realized without considering the movement of heat via an objective lens and hence they are not satisfactory for accurately retaining heat and regulating the temperature of the object of observation particularly when the specimen is observed via an immersion objective lens.
Then, a large outer frame needs to be used for the immersion objective lens to give rise to a problem of difficulty in terms of assembly, maintenance and the operation of adjusting the focal position.

first embodiment

[0016]FIG. 1 is a schematic illustration of the optical analyzer that is observation apparatus (optical analyzer) having a thermoregulation mechanism according to the present invention, showing the configuration thereof. FIG. 2 is a schematic detailed cross-sectional view of the liquid receiving frame of the optical analyzer of FIG. 1.

[0017] The optical analyzer 1 comprises as major components thereof two light sources 2a, 2b, an inverted-type fluorescent microscope 3, a liquid supply / collection unit 4, a measurement data processing section 5 and a control section 6 and is externally provided with a personal computer that operates as a processor section 7 and a display section 8.

[0018] The light sources 2a, 2b are typically a laser beam generator and the laser beams emitted from the light sources 2a, 2b are combined and made to enter the inverted-type fluorescent microscope 3 via an optical path formed by filters 11a, 11b, a mirror 12a and a dichroic mirror 12b.

second embodiment

[0030]FIG. 3 is an apparatus having a microscope feature (e.g., inverted-type microscope) that is observation apparatus having a thermoregulation mechanism according to the present invention, showing the configuration thereof. A thermoregulation mechanism according to the present invention can be applied to the inverted-type microscope 51 when the latter is used to observe an object of observation by using a glass dish 52. Like the above-described embodiment, immersion liquid 30 is supplied between the dish 52 and the immersion objective lens 13 to maintain and regulate the temperature of the immersion liquid 30 by means of a heater (the heater 43 in FIG. 2). Note, however, that the pump 33 may be omitted so that the operator may manually supply immersion liquid.

[0031] While an inverted-type microscope 51 is used as an observation apparatus of the above-described embodiment, this embodiment of thermoregulation mechanism can be applied to an erect microscope employing an immersion ob...

Abstract

An observation apparatus comprises a thermoregulation mechanism including a liquid receiving frame (28) that has a heater (43) for heating the outer frame of an immersion objective lens (13) and adapted to heat and maintain the temperature of the immersion liquid (30) contained in the frame (28) by means of the heater (43) and via the outer frame of the immersion objective lens (13) so as to maintain the temperature of the specimen (34) in the container at a constant level by utilizing heat conduction. The thermoregulation mechanism of the observation apparatus is so adapted that, when the temperature of the immersion liquid (30) decreases during a measurement/observation operation due to discharge of heat, the liquid (30) is heated again by the heater (43) to prevent the temperature of the specimen (34) from changing and maintain the temperature at a constant level.

Description

TECHNICAL FIELD [0001] This invention relates to an observation apparatus having a thermoregulation mechanism for the liquid containing an object of observation. Such an observation apparatus can suitably be used for an optical analyzer or a microscope. BACKGROUND ART [0002] Generally, when observing molecules floating in a liquid specimen with an observation apparatus such as a microscope, the temperature of the solution is preferably held to a constant level for observation because the motion of molecule is influenced by a temperature change of the solution. Various thermoregulation mechanisms have been proposed to date to keep the temperature of solution to a constant level. [0003] For instance, Jpn. U.M. Appln. Publication No. 60-156621 discloses a microscope equipped with a table provided with a thermoregulation apparatus comprising a heat emitting section for heating the container of the specimen. Jpn. U.M. Appln. Publication No. 3-25598 discloses a culturing device to be used...
